Protocol

Students will use a GLOBE Soil Fertility Kit to prepare samples and determine whether nitrate, phosphate, and potassium are absent from a soil sample or present in low, medium or high concentrations.

Supporting Protocols

Protocols to help in completion of the main protocol
Students will use a technique chosen by their teacher to expose a soil profile for characterization.

Field Guides

Step-by-step instructions for collection data according to the protocols.

Data Sheets

Sheets to be filled out during data collection

Learning Activities

Activities to help students learn more about the instruments and protocols
Students will understand the geologic phenomena of weathering and erosion. These processes, along with deposition, shape our landforms and contribute to the development of parent material in the soil formation process.
An activity which highlights the importance of learning about the soils on Earth. In this activity students explore some of the many uses of soils, learn the five soil-forming factors, and gain a better understanding of how little of Earth's surface is covered in soil.
